More than a third of the world’s population don’t have access to clean, safe toilets. It’s a humanitarian and global health hazard, that the world bank drains $260 billion off the global economy each year.

That’s where John Koeller comes in. He’s principal engineer at Maximum Performance, a company who tests toilet efficiency, using its own – ahem—patented material.

While towns and regulators haggle over the cost of improving waste water treatment, time may be running out for the Great Bay estuary.
